Market Structure and International Trade: Business Groups in East Asia

In this paper we study the effect of market structure on the trade performance of South Korea, Taiwan, and Japan. We center our analysis on Korea and Taiwan, countries which have very different market structures: Korea has many large, vertically-integrated business groups known as chaebol, whereas business groups in Taiwan are smaller and horizontally-integrated in the production of intermediate inputs. The exports of these countries to the United States are compared using indexes of product variety and 'product mix', which are constructed at the 5-digit industry level. It is found that Taiwan tends to export a greater variety of products to the U.S. than Korea, and this holds across nearly all industries. In addition, Taiwan exports relatively more high-priced intermediate inputs, whereas Korea exports relatively more high-priced final goods. We argue that these results confirm the importance of market structure as a determinant of trade patterns.

Entrepreneurial younger farmers and the “Young Farmer Problem” in England

In this paper we investigate the “Young Farmer Problem” in Europe with a specific focus on how it applies in England. Recent reforms of the European Union’s (EU) Common Agricultural Policy (CAP) have specifically targeted young farmers for increased support; with young farmers being seen as more innovative, entrepreneurial and amenable to change. Furthermore, the EU has stated that the “generational renewal” of agriculture is critical for the long term viability of the sector. This paper investigates the business performance and entrepreneurial behaviour of younger farmers in England through empirical analysis of Farm Business Survey (FBS) data, and finds some evidence to support the notion of higher levels of performance among younger farmers. Farmers in the 35 - <45 years age group showed consistently higher levels of overall productivity, profitability and investment. Additionally, the results show that younger farmers demonstrate consistently higher levels of engagement with agri-environment schemes. This study concurs with the findings of Zagata and Sutherland (2015) in the need to improve targeting on the basis of age specifically in order to isolate the under 40 age group which is the focus of European policy and in the need to separate new entrants from inheritors in the assessment of young farmers. This paper and its supportive research builds on the fifth research objective of the Research platform proposed by Zagata and Sutherland (2015) to test the characterisation of young people and new entrants to farming, as entrepreneurial innovators sympathetic to and amenable with the goals of the CAP

Microgeographic Variation in the Mexican Vole, Microtus mexicanus

Altitudinal variation was assessed in 115 (62 male; 53 female) Mexican voles (Microtus mexicanus) from six localities in Jalisco, Mexico. Univariate and multivariate statistical techniques were employed in the data analyses. A total of 49 skeletal measurements were investigated, and of these, 17 showed significant interlocality variation. Rostral breadth, depth of braincase, rostral height, width of third molar and nasal length were found to be the most variable characters. Component I (a size factor) accounted for 36% of the total phenetic variation; components II and III accounted for 30% and 19%, respectively. Larger individuals were found to occur at lower altitudes; smaller individuals occurred at higher altitudes. Size variation was expressed in reverse to Bergmann\u27s Ecogeographical Rule

Experimental demonstration of a light-ray-direction-flipping METATOY based on confocal lenticular arrays

We show, theoretically and experimentally, that a sheet formed by two confocal lenticular arrays can flip one component of the local light-ray direction. Ray-optically, such a sheet is equivalent to a Dove-prism sheet, an example of a METATOY (metamaterial for light rays), a structure that changes the direction of transmitted light rays in a way that cannot be performed perfectly wave-optically.Comment: 5 pages, 6 figure

G97-1313 Designing Preventive Health Management Programs for Cattle Producers

The NebGuide details recommendations for a beef cattle herd immunization program. This NebGuide presents two flow sheets which detail the recommendations for a beef cattle herd immunization program: the Calf through Weaning Preventive Health Management Flow Sheet and the Heifers, Cows and Bulls Preventive Health Management Flow Sheet. While this NebGuide emphasizes the procedures conducted on cattle at each cattle handling opportunity, it is very important to note the role a high quality nutritional program plays in building a total herd health program. You are encouraged to work with a qualified beef cattle nutritionist and your veterinarian when developing your herd health program
